Map of Species Occurrences for Vitis cinerea

The map below summarizes all occurrence data at the county level. All counties within a state where are observation was described have been included. It is possible that some of the counties, even though they may not have known occurrences, should be considered habitat for a given taxon. Selecting a county will provide the name and summary of the observations within.

County Classifications Rules

Blue: color counties are of low priority for review for one of the following reasons:
- germplasm sample has been collected from the county after 1970
- Two herbarium samples have been collected from the county after 1970
- The county was identified by USDA Plants or Bonap and contains at least one herbarium record
- The county was indentified by Nature Serve


Orange: color counties are of high priority for review for one of the following reasons.
- All observations were made before 1970
- A single herbarium record was noted after 1970
- Only observational data has been noted within the county.
- Only defined by USDA Plants

Grey: color counties are locations where no observations have been noted but an observation has been recorded in the state. This is mostly here so individuals can identify counties worth of inclusion despite the lack of observational data.

Classification of Observational Data

Orange: color points represent observational data, such as iNaturalist reports.


Blue: colored points represent herbarium data


Green: colored points represents gremplasm sample. Most species do not have any germplasm records.
